The following describes a method for selecting solder provided in the embodiments of the present application by taking an execution subject as a user equipment as an example.
Referring to fig. 1, which is a flowchart of a method for selecting a brazing filler metal provided in an embodiment of the present application, the method for selecting the brazing filler metal includes steps S101 to S103, where:
s101: acquiring attribute information of various brazing fillers;
s102: determining a wettability parameter corresponding to each brazing filler metal based on the attribute information of each brazing filler metal;
s103: and selecting the brazing filler metal of which the corresponding wettability parameter meets the preset selection condition from a plurality of brazing filler metals as the target brazing filler metal based on the wettability parameter corresponding to each brazing filler metal.
According to the embodiment of the application, the spreading area coefficient of each brazing filler metal is calculated to serve as the corresponding wettability parameter, and the brazing filler metal with the best wettability is determined based on the wettability parameters of the brazing filler metals, so that the use efficiency in an experiment or a manufacturing process is improved.
The following describes each of the above-mentioned steps S101 to S103 in detail.
In step S101, the property information is an inherent property and a measured property of the brazing filler metal, where the inherent property includes identification information such as a name of the brazing filler metal, for example, an a alloy brazing filler metal, or an XXX brazing filler metal, and further includes inherent property information such as a density of the brazing filler metal. The measurement attributes comprise the characteristics of the solder, such as quality and the like, and also comprise area data of each solder after spreading on the surface of the base metal, which is obtained through measurement.
The area data after spreading on the surface of the base material is that the brazing filler metal is placed on the base material, the brazing filler metal can present a certain shape after spreading, most of the brazing filler metal is irregular, and the corresponding graph area is the area data of the brazing filler metal after spreading on the surface of the base material.
In step S102, when the plurality of attribute information are acquired, the wettability parameter corresponding to each solder material can be calculated based on the attributes.
In the prior art, the method for calculating the wettability of the solder is generally as follows: the solder wettability is evaluated by adopting a spreading coefficient in the standard GB/T11364-2008 solder wettability test method.
The method specifically comprises the following steps: and (3) measuring the thickness of the copper plate before the solder is spread and the total height of the sample after the solder is spread by adopting a micrometer, further measuring the height of the solder after the solder is spread, calculating the spreading coefficient according to a formula (1), repeating the test for 5 times, and taking the average value of the result.
Figure BDA0002606719290000091
Wherein K represents a spreading factor; h represents the numerical value of the height of the brazing filler metal after spreading on the surface of the base metal; d represents the diameter of a sphere having the same volume as the solder, and D is 1.24V1/3(ii) a V represents the ratio of mass to density of the solder used in the test.
Under ideal conditions, the traditional classical binary or ternary alloy brazing filler metal is usually eutectic or near-eutectic alloy, the melting temperature range of the brazing filler metal is small, the fluidity is good, the brazing filler metal is mostly in a spherical segment shape or an approximate spherical segment shape after being spread, and the height H of the brazing filler metal after being spread on the surface of a base metal can be accurately measured. However, with the development of new structural design and new materials for brazing, structural materials for brazing are diversified and heterogeneous, the requirements on the wettability of brazing filler metal are very strict, and the requirements can be met by adopting multi-component alloy component design at present. The developed multi-element alloy solder has the characteristics of large melting temperature range, large influence of base metal components and surface states on the wettability of the solder and the like, and the spread solder is in an irregular shape under the actual working condition, so that the spread height of the solder is large in numerical deviation, and the calculated spreading coefficient cannot accurately reflect the wettability of the solder. Therefore, in order to solve the above problems, a new calculation method for evaluating the wettability of the solder is needed to evaluate the wettability of the solder in practical tests more accurately.
Because the spreading area of the solder is measured accurately, whether the detected area can be utilized or not is assumed in the embodiment of the application, and the wetting performance is represented by the calculated spreading area coefficient.
The assumed spreading area coefficient calculation method specifically comprises the following steps: and determining the solder spreading area coefficient, namely the wetting property parameter of each solder based on the corresponding quality and density parameter of each solder and the area data of each solder spread on the surface of the base metal.
Specifically, the volume data corresponding to each solder can be determined based on the mass and density parameters corresponding to each solder, and the projection area of the data sphere having the same volume as each solder can be obtained based on the volume data corresponding to each solder.
Wherein, the calculation formula of the projection area of the sphere with the same volume data with each solder is shown as formula (2):
S=0.604V2/3; (2)
wherein S represents a projected area of a sphere having volume data equal to each solder, and V represents volume data corresponding to each solder.
The method for acquiring the area data of each brazing filler metal after spreading on the surface of the base metal comprises the following steps: firstly, measurement scanning is carried out through an integrator, and software measurement calculation is carried out on a graph obtained by scanning, and the method specifically comprises the following steps:
referring to fig. 2, fig. 2 is a schematic view of solder spreading in an ideal case. As shown in fig. 2, the solder spreading pattern Δ ABO has the following relationship, as shown in formulas (3) and (4):
Figure BDA0002606719290000101
Figure BDA0002606719290000102
from equation (4), C, S related to the spreading area coefficient can be expressed by m and H, as shown in the following equations (5), (6), (7):
Figure BDA0002606719290000103
C=πL2=π(2m-1)H2; (6)
Figure BDA0002606719290000104
wherein C represents the numerical value of the area of the brazing filler metal spread on the surface of the base material; s represents the projection area of a sphere with the volume equal to that of the brazing filler metal; m represents the solder mass.
After all target parameters, namely the projection area of a sphere with the same volume data as each solder and the area data of each solder after spreading on the surface of the base metal are obtained, the spreading area coefficient of each solder can be calculated.
Wherein, the calculation formula of the spreading area coefficient is as follows:
Figure BDA0002606719290000111
wherein M is the spreading area coefficient, C is the area data of each brazing filler metal after spreading on the surface of the base metal, and S is the projection area of a sphere with the same volume data as each brazing filler metal.
In order to verify the relationship between the area spreading coefficient and the spreading coefficient in the conventional calculation method, in the embodiment of the present application, the spreading coefficients are substituted by the formulas (3), (4), (6), and (7), and the corresponding spreading coefficient and spreading area coefficient are respectively expressed as shown in formula (9):
Figure BDA0002606719290000112
it can be found that both the spreading factor and the spreading area factor are quantities related only to the wetting angle θ, and decrease as θ increases, and thus it can be found that there is a certain correlation between the spreading factor and the spreading area factor.
In order to further verify the reliability of the spreading area coefficient for verifying the wettability, in the embodiment of the present application, different qualities of the Sn58Bi alloy and the solder paste were respectively taken to perform the spreading test, and the K and M values were calculated. It was found that the spreading area coefficient was substantially the same as the spreading tendency of Sn58Bi, to which the spreading coefficient is reflected. And linear fitting is carried out on the spreading area coefficient and the spreading coefficient, and the reliability of the fitting result is high. The good corresponding relation between the spreading area coefficient M and the spreading coefficient K is demonstrated, so that the spreading area coefficient can be used as one of indexes for measuring the wettability of the brazing filler metal, namely, the positive correlation between the spreading area coefficient and the wettability is verified.
Thirdly, in the above S103, since there is a certain mapping relationship between the spreading area coefficient and the wetting performance parameter, the wetting performance parameter can be determined by the spreading area coefficient of the solder.
Specifically, the mapping relation between the spreading area coefficient and the wettability parameter is that the spreading area coefficient is positively correlated with the wettability parameter, and the corresponding solder with the spreading area coefficient meeting the preset selection condition is selected from various solders based on the corresponding spreading area coefficient of each solder to serve as the target solder.
According to the embodiment of the application, the spreading area coefficient of each brazing filler metal is calculated to serve as the corresponding wettability parameter, and the brazing filler metal with the best wettability is determined based on the wettability parameters of the brazing filler metals, so that the use efficiency in an experiment or a manufacturing process is improved.
It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
